VkExternalMemoryFeatureFlagBitsNV

Bits which can be set in VkExternalImageFormatPropertiesNV::externalMemoryFeatures, indicating properties of the external memory handle type, are:

typedef enum VkExternalMemoryFeatureFlagBitsNV {
    VK_EXTERNAL_MEMORY_FEATURE_DEDICATED_ONLY_BIT_NV = 0x00000001,
    VK_EXTERNAL_MEMORY_FEATURE_EXPORTABLE_BIT_NV = 0x00000002,
    VK_EXTERNAL_MEMORY_FEATURE_IMPORTABLE_BIT_NV = 0x00000004,
} VkExternalMemoryFeatureFlagBitsNV;

pub struct ExternalMemoryFeatureFlagBitsNV(u32);
impl ExternalMemoryFeatureFlagBitsNV {
    pub const DEDICATED_ONLY: Self = 0x00000001;
    pub const EXPORTABLE: Self = 0x00000002;
    pub const IMPORTABLE: Self = 0x00000004;
}

• VK_EXTERNAL_MEMORY_FEATURE_DEDICATED_ONLY_BIT_NV specifies that external memory of the specified type must be created as a dedicated allocation when used in the manner specified.
• VK_EXTERNAL_MEMORY_FEATURE_EXPORTABLE_BIT_NV specifies that the implementation supports exporting handles of the specified type.
• VK_EXTERNAL_MEMORY_FEATURE_IMPORTABLE_BIT_NV specifies that the implementation supports importing handles of the specified type.
